Controlled Data Releases

Ontario Neurodegenerative Disease Research Initiative (ONDRI): Parallel pathways for language processing: functional dissociation and compensation release

Dr. Jed Meltzer, Dr. Regina Jokel, Dr. Jean Chen, Dr. Morris Freedman, Dr. Jennifer Ryan, Dr. Aneta Kielar
This controlled data release contains data from a series of studies conducted at Baycrest Hospital concerning the role of dorsal and ventral language pathways in both brain hemispheres in language processing. The studies examined neural reactivity to semantic and syntactic anomalies in written and auditory presentation formats, although some used written presentation only.

CP-NET Clinical Database Platform: Genomic Architecture of CP (Whole Genome Sequencing)

Cerebral Palsy Neuroscience Discovery Network (CP-NET)
The CP-NET Clinical Database recruits children born in 2009 or later with a confirmed diagnosis of cerebral palsy (CP) and contains data on clinically relevant risk factors, neuroimaging information, and neurodevelopmental functioning including psychosocial and participation outcomes.

This released dataset has whole genome sequencing data (WGS) on 221 children and youth with CP and their biological parents (656 samples). WGS was performed on DNA extracted from saliva on the Illumina HiSeq X platform, and the resulting CRAM files are provided.

EpUp Study: A Pilot Intervention for People with Epilepsy & Depression

Hum, K. M., Chan, C. J., Gane, J., Conway, L., McAndrews, M. P., & Smith, M. L.
About one third of people with epilepsy experience comorbid depression. UPLIFT (Using Practice and Learning to Increase Favorable Thoughts) uses mindfulness-based cognitive behavioural therapy (CBT) principles to treat depression in people with epilepsy. The EpUp study aimed to examine outcomes of UPLIFT versus EpINFO, an epilepsy information and self-management program. The effects of these distance-delivery, group intervention programs were studied in adults with epilepsy and self-reported depressive symptoms...

5P: Predicting Persistent Postconcussive Problems in Pediatrics

Dr. Roger Zemek, Dr. Martin Osmond and the Pediatric Emergency Research Canada (PERC) Concussion Team
Concussion is a common injury occurring in children and adolescents, and results in a wide variety of effects spanning physical, cognitive (thinking), psychological/behavioural, or sleep. While most cases of concussion improve within weeks, approximately one third of children have on-going symptoms for longer than 1 month, known as persistent post concussive symptoms (PPCS)...
